Steel I-Profile¶

This notebook demonstrates how to create and visualize steel I-profile (I-beam) shapes using the Blueprints library. The I-profile is a common structural steel section, shaped like the capital letter 'I', with two horizontal flanges connected by a vertical web. This geometry efficiently resists bending and shear forces, making it ideal for beams and columns in construction and engineering.

We will:

• Import required libraries and modules
• Create, plot and and display the section properties of an standard I-profile
• Import the required I profile section library
• Create, plot and and display the section properties of custom I profile

Key Parameters of an I-Profile:

• Top flange width and thickness: The upper horizontal plate
• Bottom flange width and thickness: The lower horizontal plate
• Web thickness: The vertical plate connecting the flanges
• Total height: The overall height from the bottom of the lower flange to the top of the upper flange
• Radii: Fillet radii at the junctions between web and flanges for stress reduction
• Steel material: Defines the mechanical properties (e.g., yield strength)

1. Import Required Libraries and Modules¶

First, import the relevant classes from the Blueprints library for I-profiles and HEB standard profiles.

In [1]:

from blueprints.structural_sections.steel.standard_profiles import HEB

from blueprints.structural_sections.steel.standard_profiles import HEB

2. Create Standard HEB-Profile¶

Instantiate a standard HEB using a predefined HEB600 profile.

In [2]:

heb_profile = HEB.HEB600

heb_profile = HEB.HEB600

3. Specify corrosion (optional)¶

You can specify corrosion allowance for the profile if needed.

In [3]:

heb_profile = heb_profile.with_corrosion(corrosion=1.5)

heb_profile = heb_profile.with_corrosion(corrosion=1.5)

4. Plot Standard I-Profile¶

Generate a plot of the standard I-profile using the plot() method.

In [4]:

plot = heb_profile.plot(show=True)

plot = heb_profile.plot(show=True)

Ignoring fixed x limits to fulfill fixed data aspect with adjustable data limits.

5. Access Standard I-Profile Properties¶

Retrieve the section properties of the standard I-profile using the section_properties() method.

In [5]:

properties = heb_profile.section_properties()

properties = heb_profile.section_properties()

6. Create Custom I-Profile¶

You can also define a custom I-profile by specifying all geometric parameters.

In [6]:

from blueprints.structural_sections.steel.profile_definitions import IProfile

custom_i_profile = IProfile(
    top_flange_width=300,  # mm
    top_flange_thickness=20,  # mm
    bottom_flange_width=200,  # mm
    bottom_flange_thickness=10,  # mm
    total_height=600,  # mm
    web_thickness=10,  # mm
    top_radius=15,  # mm (fillet radius at top flange)
    bottom_radius=8,  # mm (fillet radius at bottom flange)
)

from blueprints.structural_sections.steel.profile_definitions import IProfile custom_i_profile = IProfile( top_flange_width=300, # mm top_flange_thickness=20, # mm bottom_flange_width=200, # mm bottom_flange_thickness=10, # mm total_height=600, # mm web_thickness=10, # mm top_radius=15, # mm (fillet radius at top flange) bottom_radius=8, # mm (fillet radius at bottom flange) )

7. Plot Custom I-Profile¶

Generate a plot of the custom I-profile using the plot() method.

In [7]:

plot = custom_i_profile.plot(show=True)

plot = custom_i_profile.plot(show=True)

Ignoring fixed x limits to fulfill fixed data aspect with adjustable data limits.

8. Access Custom I-Profile Properties¶

Retrieve the section properties of the custom I-profile using the section_properties() method.

In [8]:

properties = custom_i_profile.section_properties()

properties = custom_i_profile.section_properties()
